Essential
What we're looking for
- Strong application-development experience, enough real-world app-dev depth to define how applications should be built well, and to encode that as patterns and quick starts others rely on. This is the core of the role.




- Strong AWS application development and software engineering experience, ideally on developer tooling, delivery platforms, or cloud-native developer workflows.
- You already use AI daily for engineering work. You build with a coding harness/agent as a matter of course, and the more experience you have driving one, the closer to spec-driven development, the better. This is central to how we work, not a bonus.
- Solid knowledge of AWS serverless and event-driven services:
- Lambda
- API Gateway
- Step Functions
- Integration patterns across AWS services
- Experience automating CI/CD, SDLC, and engineering controls:
- GitHub Actions
- Infrastructure as Code
- Automated evidence capture
- Experience building automated governance, compliance, or operational controls into delivery pipelines, turning policy and regulatory requirements into code and evidence.
- Comfortable implementing both:
- Deterministic scripted checks
